OSHA does not mandate AEDs in all workplaces but strongly encourages them when emergency response could exceed three to five minutes, a key part of first-aid compliance.
If you manage workplace safety, you have researched OSHA requirements for AEDs, and the official answer may surprise you. Yet the first-aid rule at 29 CFR 1910.151(b) requires trained responders and adequate supplies when a workplace lacks a nearby clinic or hospital—and for cardiac emergencies, an AED is widely considered part of adequate first aid. Employers who assume no mandate means no action can find themselves unprepared during an audit or an actual emergency. This article covers what OSHA requires, when an AED becomes a compliance concern, and what a defensible program looks like.
OSHA’s AED Requirements: What The Rules Actually Say
No general-industry OSHA standard says “you must have an AED.” The compliance trigger comes indirectly through 29 CFR 1910.151(b): if your workplace has no infirmary, clinic, or hospital in near proximity, you must have trained personnel and adequate first-aid supplies. Industry consensus, backed by OSHA’s guidance, treats an AED as part of those adequate supplies when cardiac arrest is foreseeable and EMS cannot arrive within minutes.
OSHA’s clearest AED-specific language appears in Appendix A to 1915.87, a maritime regulation. It says employers who provide AEDs should designate trained users, keep devices within three to five minutes of an incident report, and maintain them per manufacturer specifications. Compliance summaries treat this as best practice across general industry.
Does Your Workplace Actually Need an AED?
The deciding factor is EMS proximity. If your workplace sits minutes from a hospital or rapid-response fire station, OSHA’s expectation for an on-site AED is lower. But if worksites are remote, spread across large campuses, or stacked across multiple floors where professional responders cannot reach a collapsed employee within three to five minutes, the first-aid rule pushes toward AED placement. A common scenario: a multi-story office building where the closest hospital is four minutes away by ambulance, but getting a stricken employee from the fifth floor to the loading dock pushes the total past the critical window.
Some industry-specific OSHA standards carry CPR-related requirements—logging, electrical power generation and transmission, permit-required confined spaces, and commercial diving. None create a blanket AED mandate, but they reinforce that employers must prepare for cardiac emergencies wherever work creates elevated risk or delayed response.
Building a Compliant AED Program
A defensible AED program goes beyond purchasing a device. OSHA-oriented guidance points to five core elements.
| Program Element | What It Requires | Common Mistake |
|---|---|---|
| Place AEDs within 3–5 minute reach | Map response time from every work area to the nearest AED | Mounting centrally with no coverage in distant or multi-floor zones |
| Designate and train users | Pick specific employees and train them in AED operation plus CPR | Assuming untrained bystanders will manage; training measurably improves survival |
| Inspect and maintain per manufacturer specs | Check battery status, pad expiration, and software updates on a regular schedule | Letting pads expire or batteries drain without an alert system |
| Follow state and local laws | Some states add AED mandates, registration, or notification requirements beyond federal rules | Relying only on OSHA’s silence while missing binding state or local obligations |
| Establish medical oversight | Non-OSHA guidance recommends a written program with a responsible medical director | Treating device ownership as the full compliance picture without program structure |
The most common failure is treating AED ownership as equivalent to compliance. Without training, placement planning, and maintenance, a wall-mounted AED provides limited protection. Another frequent miss: failing to position units so responders can reach any incident within the three-to-five-minute window, especially in facilities with mezzanines, separated buildings, or high-rise floors.

FAQs
Does OSHA fine companies for not having an AED?
However, if a cardiac emergency occurs and the employer failed to provide adequate first-aid resources under 29 CFR 1910.151(b) where EMS was not near, OSHA could cite the broader first-aid deficiency.
Which Workplaces Need AEDs Most Under OSHA Guidance
OSHA’s guidance points most strongly to workplaces where EMS cannot reach a collapsed employee within three to five minutes—remote construction sites, large industrial campuses, multi-story office towers, and any facility with delayed response. The maritime appendix makes this expectation explicit, and the same logic applies across general industry.
AED Training Obligations Under OSHA
But if an employer provides AEDs, OSHA guidance says to designate who will use them and train those individuals properly. Training improves outcomes even on devices designed for untrained users, especially when combined with CPR in a coordinated emergency plan.
